Question

in in triangle abc if ab is equal to AC and angle b is equal to 65 degree find angle A​

Answer 1

Angle c = angle b

because angles opposite to equal sides are equal

so angle c = 65°

angle a = angle a + angle b + angle c = 180

angle sum property of triangle

angle a + 65° + 65° = 180°

angle a = 180 - 130

angle a = 50°

hope it helps

please mark me brainliest answer

Answer 2

Answer:

A=50°

Step-by-step explanation:

in a triangle angleB=angleC

so,BY ANGLE SUM PROPERTY OF TRIANGLES;

A+B+C=180°

THUS,A+65+65=180

=A+130=180

=A=180-130

=A=50
